This invention relates'to separable end stop couplings of separable fastener stringers providingkcomplete separation of the two stringers.v More particularly, .the'invention relates to an end stop. coupling having alatching element nor- Imally retaining the stringers in` coupled relation-` ship and movable into unlatched position to prothe slider in providing separation of the stringers at said end portion thereof. 'I'he novel features of the invention will be best-understood iromthe following description when taken together with the accompanying drawingin which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suit'- able reference .characters in each of the views. andin which: l

Fig. 1 is a plan view'of a separable fastener made according to' my invention with part o! the construction broken`away and part in section.

Fig. 2 is a section on the line 2-2 of. Fig. 1.

Fig. 3 is a view similar to Fig. 2 showing the parts in unlatched position, and

Fig. 4 is a perspective view of the latching end of one Stringer. 1 In separable fasteners of the kind' lunder consideration, 'it has been common to provide two separableend stop couplingsgenerally referred to as-a -box part on one Stringer and a-pin part on the other Stringer entering th boxpart in coupling the stringers and providing complete separation of the stringerswhen the slider is brought into engagement with the box part. In certain vide separationof the stringers independent of fis tos'ay. scoops To show one adaptation of the invention, -I have illustrated fn Fig. lot the drawingspaced portions of two stringers i and Ii,to the beaded edges i2 anddl'3 of which are attached links or scoops I4 and I6' of the double action type, that .having common coupling suriaces at opposed sides thereof so that a slider i6 may be moved in either directionon the lstringers tocouple the scoops, and -in like manner, in uncoupling the same.

\ In Fig. l, the slider I8 is shown at one, end

. portion of the partially Acoupled stringers. Se-

cured to the beaded edge of the other endportion oi the sjtringer is a pin part I1. and a box I part i3. The pin partl il extends alongthe bead i2 and'it includes at the outer surface thereof a projecting rib i3 terminating in a link engaging enlargement 'to engage the end uses of separable fasteners, particularly Aon long l jackets, coats and other garments or wraps, itis desirable to 'openthe lower portion of the garfme'nts while maintaining the .upperportion-'thereparticularly when the wearer is 4ln a of closed,

sitting positin l To adapt fasteners for .such use, I provide a separable end stop coupling comprising a-box part' onone stringer and a pi'n part -on theother.

`Stringer withlatching means normally retaining said parts in coupled relationship, whereby in manually for. .otherwise moving the latching means into inoperative position. the pin and box parts may be `separated touncouple ersl independent oi' thel usual. slider. f 'This end link'2i of thestringer il.

The Abox part i8 comprises a pin portion22 arranged along the beaded. edge i3 and -at the Aend of the stringer, the part 23 extends laterally beyond the strlnger edge to formtop and bottom' walls 23 Aand 26 of ,thebox' part, these walls be ing joined in the endof the box part in anend wal125 having apertures 2 6 therein.

t The top-wall 23 of the Ibox part I8v is spaced iroxnthe surface 2l o! the pin portion 22 to form a clearance or channel. 23, which provides free vertical movement of aL latch element 29 in the.

box part.

.` In the construction shown, the latch element comprises a plate-which fits within the longitudinal dimensions of the top wall and has at the 'outer side thereof a hooked flange 30 to engage the shoulder portion 3| of the pin part i1, as clearly seen -in Fig. 2 of the drawing.

` Extending vertically `through the pin portion at 36.- This pin projects beyond the surface' of the bottom 'wallzl and -has a cup-shaped head 35, which forms-a seat for h spring 38 arranged'.

the string; f

stop coupling construction is further applied to. l

stringersfhaving kdou-ble action scoops capable oi being coupled and uncoupled'by a slider movable in either direction on the stringers., thereby facilitating recoupling'of thestringers which have been separated through the release ofthe latchingllleans.v Y w a is an apex-turen, in which is mounted a pin or plunger't. the upper end of which is riveted or otherwise secured to the element 23, as seen onfthepin and engaging-'the'bottom wall 24. "I'he top wall'23 also joins the pin part 22 in a sidewall 31; :the top wall 23also has an aper- -ture 38 in valinementjwith the pin 33,l or the` rivet head'3l thereofpto provide clearance for this head,- thus Aminimizing the amount of clearanceyprovided' vin thej channel23ror the free operation of thelatchingl'element. In'this -connec'- tion. it will'be understood .that-any type and kind of' latchinselement can be employed, as well as any-means ioractuating the same depending entirely upon the use to which the fas'- tener. is applied and the question of cost of the complete latching equipment. The illustration t vin the accompanying drawing is simply' to show one simple adaptation oi' the invention.

In the normal use of the fastener, the string- I ers will be coupled and uncoupled 'by the slider i8 in the usual manner. In other words, to completely separate the stringers, the slider will be moved from the position shown in Fig. 1 in the direction o f the pin and box parts I1 and'- Is, the

contracted end ofA the slider being checked in this movement by the top and bottom walls Il and 24 as well as the wall 31. When the slider .is in this position, the pin part Il is free to be drawn through the slider` channel and the stringers are separated leaving the slider on the strinserJ i I adjacent the box part Il. In recoupling the stringere, the pin part isinoero through the slider and into the box part and the slider is then 'moved away from the pin and recoupling thelinks Il and Il.

In the auxiliary or supplemental use .of the stringere, in other words `when Vitis desirable to separate the end portionsI of the stringers having the pin part Il and box partis without uncoupling apredetermined part of the'other end portion of the' stringers, all that 'will be necessary is for the wearer to depress Vthebutton 38 which will raise the latchfelement 29 out chengagement with the pin part I1, thus providing free lateral movement of the pin part I1 through thel box part, as indicated in Fig. 3 of the drawing. The links Il and It may then be uncoupled 'by simply pulling on the stringers .to any desired degree. While itis possible to recouple the stringers by hand, it would be quicker to move the slider downwardly along vthe stringers to recouple the lower end portion of the stringers,

allowingthe pin part l1 to freely 'enter the box Dart with the latch elementI-fin raised position and thereafter the slider may be moved in the opposite direction along the stringers to recouple the entire stringer length.

' The latch element 2! may be said to comprise Y a supplemental Awall vof the box part which is interposed between vthe outer'walls and movable ltoward and from one of'these walls to vary the spacing between thewalls. This supplemental 50 the pin part to normallyY retain the pin aainst lateral displacementfrom -the box part.

However, by increasing the spacing between the wallvincludes the retaining flange which engages walls by movement of said supplemental wall; its flange clears the pin part to provide free .lateral separation of the pin'and box parts.

It will be understood that the' surface 21 of the pin portion 22' of the box part il serves as a in th direction of the wall 2|. It will thus be apparent that the pin 'part `l'|- may besnapped into locked'DOition-without having to first mandually raise the element 2l.
